Confused! Positive OPK at CD40...?

Nadia

Hi! My period is usually spot on about 30-33 days with ovulation usually at day 18-19. I am fairly sure I had a positive OPK at day 19 of this cycle. Im now 7 days late according to Glow with plenty of negative pregnancy tests so I can rule that out. I did an OPK last night and another one today.. which I believe is positive. Has this happened to anyone else? I am ovulating twice with a skipped period? Thank you ladies!
